The c2f type double flange loose sleeve power transmission joint is composed of flange loose sleeve expansion joints, short pipe flanges, power transmission screws, and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate for pipeline installation errors. The double flange loose sleeve power transmission joint cannot absorb axial displacement. Double flange loose coupling is mainly used for loose coupling of accessories such as pumps and valves.

Introduction to Double Flange Loose Sleeve Power Transmission Joint
C2F type double flange loose sleeve power transmission joint is composed of flange loose sleeve expansion joint, short pipe flange, power transmission screw, and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate for pipeline installation errors. The double flange loose sleeve power transmission joint cannot absorb axial displacement. Double flange loose coupling is mainly used for loose coupling of accessories such as pumps and valves.
Performance characteristics of double flange loose sleeve power transmission joint
Loose sleeve force transmission joint is formed by adding flange short pipe and force transmission screw on the basis of flange loose sleeve compensation joint. This type of compensation joint is different from loose sleeve compensation joint and loose sleeve limit compensation joint in that its compensation amount refers to the adjustment amount during installation and disassembly. Once all nuts are tightened, it is rigidly connected and can transmit axial force, thereby protecting valves, pumps, and other equipment.
Double flange loose sleeve power transmission joint is suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and particulate powder with a temperature not higher than 250 degrees Celsius.
Double flange loose sleeve power transmission joints are suitable for connection with flanges on both sides. During installation, adjust the installation length between both ends of the product and the pipe or flange. After installation and welding, tighten the gland bolts diagonally and uniformly to make them a whole, with a certain amount of displacement, for installation and maintenance, which can be adjusted according to on-site dimensions. During operation, the axial thrust can be transmitted to the entire pipeline.
Material of loose sleeve power transmission joint: mainly Q235 carbon steel, stainless steel, cast steel, ductile iron, etc. Choose different materials and models for different purposes.
The types of loose sleeve power transmission joints include: single flange loose sleeve power transmission joints, double flange loose sleeve power transmission joints, and removable double flange loose sleeve power transmission joints.
